ID3D12DescriptorHeap interface

A descriptor heap is a collection of contiguous allocations of descriptors, one allocation for every descriptor. Descriptor heaps contain many object types that are not part of a Pipeline State Object (PSO), such as Shader Resource Views (SRVs), Unordered Access Views (UAVs), Constant Buffer Views (CBVs), and Samplers.
